What is endoscopic RFA?
Endoscopic RFA, also called endoscopic rhizotomy, uses a small camera to view the treatment area and radiofrequency energy to treat nerves that carry pain signals from the facet joints. It is different from a procedure that removes a herniated disc or enlarges the spinal canal.
Who may be considered?
Evaluation focuses on persistent facet-related pain, examination findings, prior treatment and response to diagnostic medial branch blocks. Imaging alone does not establish that a facet joint is the pain source.
What to expect
At our practice, RFA procedures are performed under sedation. Follow the care team’s preparation instructions and arrange an adult driver. The treatment plan and recovery restrictions depend on the spinal level and your health.
Benefits and considerations
The goal is to reduce pain and improve activity. Relief varies, and symptoms can return. Risks include soreness, bleeding, infection, nerve irritation or injury, and sedation-related complications. Endoscopic RFA is not appropriate for every cause of back pain.
